Because you're not using GTKmm > As learned in Qt if QTextEdit is inherited from QWidget then I do not have > to convert it. > Is it the same case with Gtkmm? I think this is one of the advantages of > inheritance in C++. Yes, but you're not using GTKmm. You're using the native C function from GTK+ and therefore you don't get the C++ inheritance benefits. Indeed it's worse than that, because you're passing a GTKmm class pointer to a C function that expects a GTK structure pointer. You should be writing: m_editor->modify_base ( GTK::STATE_NORMAL, mihColor ); Rob _______________________________________________ gtkmm-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkmm-list
